DETAILED DESCRIPTION

FIGS. 1-6 illustrate a level 100 for determining whether an object is level to a particular surface or adjusting an object to a level surface. The level 100 may be used to measure and level at different angles, i.e., 0 degrees, 30 degrees, 45 degrees, and 90 degrees. It should be readily apparent that the level may be used by a variety of users and skilled technicians to perform a variety of leveling functions.

As shown in FIGS. 1-3, the level 100 includes a web 105 coupled to each of a top planar surface 110, a bottom planar surface 115, a 45-degree planar surface 120, a 30-degree planar surface 125, and a back planar surface 130. The top planar surface 110 is spaced apart from and substantially parallel to the bottom planar surface 115. The 45-degree planar surface 120 is disposed at an included angle of 135 degrees relative to the top planar surface 110. The 30-degree planar surface 125 is disposed at an included angle of 150 degrees relative to the bottom planar surface 115. The back planar surface 130 is substantially perpendicular to the top planar surface 110 and the bottom planar surface 115. The back planar surface 130 is connected to the top planar surface 110 by a first connecting surface 140 and is connected to the bottom planar surface 115 by a second connecting surface 145. The first connecting surface 140 is disposed at an included angle of 135 degrees relative to the top planar surface 110. The second connecting surface 145 is disposed at an included angle of 135 degrees relative to the bottom planar surface 115. Additionally, any of the planar surfaces can include ruler markings for measuring distance.

The web 105 supports a 0-degree vial 150, a 90-degree vial 155, a 45-degree vial 160, and a 30-degree vial 165. The long axis of the 0-degree vial 150 is parallel with the top planar surface 110 and the bottom planar surface 115. The long axis of the 90-degree vial 155 is parallel with the back planar surface 130. The long axis of the 45-degree vial 160 is parallel with the 45-degree planar surface 120. The long axis of the 30-degree vial 165 is parallel with the 30-degree planar surface 125. Each vial contains a liquid, a gas bubble 170, and a series of markings 175. The vials are secured to the web 105 by threaded set screws or other means that hold the vials in place. The threaded set screws inhibit the loosening of the vials over time and also allow for easy replacement of damaged vials. Preferably, the markings 175 are laser etched on the vial and the liquid is colored (e.g., green). Laser-etched markings 175 resist wearing off over time, while the colored liquid improves the visibility of the gas bubble 170 and the markings 175.

As the angle of the level 100 (and therefore the angle of the vial) changes relative to a fixed axis, the gas bubble 170 moves within the vial along the long axis of the vial. Each vial can be used with at least one of the planar surfaces to determine the orientation of a surface or object to be leveled relative to level (i.e., the fixed axis). The position of the gas bubble 170 with respect to the markings 175 allows the user to determine the orientation of the surface or object to be leveled relative to that vial. For example, when the top planar surface 110 engages the surface or object to be leveled, the surface or object to be leveled is level when the gas bubble is centered along the long axis of the 0-degree vial 150.

As best shown in FIG. 3, a first electrical outlet perimeter 180 is formed in the web 105. The perimeter 180 is shaped like the perimeter 185 of a standard (120 volt AC) electrical outlet 187, as shown in FIG. 7. The perimeter 180 includes a top portion 190, a bottom portion 195, a first curved side portion 200, and a second curved side portion divided into two segments 202 and 204. The perimeter 180 is sized to engage at least a portion of the perimeter 185 of the electrical outlet 187 when the electrical outlet 187 is inserted within the perimeter 180. When the perimeters 180, 185 are engaged, either the 0-degree vial 150 or the 90-degree vial 155 is used to level the electrical outlet 187. Alternatively, the perimeter 180 is configured to accommodate the leveling of differently shaped electrical outlets, for example, those configured for use with different voltages or for use in other countries. The perimeter 180 allows the user to level the electrical outlet 187 without attaching a face plate to the electrical outlet 187.

A second electrical outlet perimeter 205, identical to the first perimeter 180, is formed in the web 105. The second perimeter 205 includes a top portion 210, a bottom portion 215, a first curved side portion 220, and a second curved side portion divided into two segments 222 and 224. The second perimeter 205 is spaced from the first perimeter 180 so that the two perimeters 180, 205 are separated by the standard spacing between a pair of side-by-side electrical outlets. In this way, the two perimeters 180, 205 can be used to level a pair of side-by-side electrical outlets. Alternatively, as shown in FIG. 6, the level 100 only includes one electrical outlet perimeter 180. The perimeters 180 and 205 can be formed on either side of the web 105.

A first light switch aperture 225 is formed through the web 105. The aperture 225 is positioned within the perimeter 180. The aperture 225 forms a third perimeter 230 that includes a top portion 235, a bottom portion 240, and two side portions 245. The perimeter 230 is shaped like the perimeter 250 of a housing 252 of a standard light switch 255, as shown in FIG. 8. The perimeter 230 is sized to engage at least a portion of the perimeter 250 when the housing 252 and the switch 255 are inserted into the aperture 225. When the perimeters 230, 250 are engaged, either the 0-degree vial 150 or the 90-degree vial 155 is used to level the housing 252 and the switch 255. Alternatively, the perimeter 205 is sized to engage the perimeter 257 of the switch 255. In other alternatives, the aperture 225 and the perimeter 230 are configured to accommodate the leveling of different types of switches, for example, slidable dimmer switches.

A second light switch aperture 260, identical to the first aperture 225, is formed through the web 105. The aperture 260 is positioned within the perimeter 205. The aperture 260 forms a fourth perimeter 265 that includes a top portion 270, a bottom portion 275, and two side portions 280. The second aperture 260 is spaced from the first aperture 225 so that the two apertures 225, 260 are separated by the standard spacing between a pair of side-by-side light switches. In this way, the perimeters 230, 265 of the apertures 225, 260 can be used to level a pair of side-by-side light switches. Alternatively, as shown in FIG. 9, the level 100 only includes one light switch aperture 225.

As shown in FIGS. 2 and 5, the back planar surface 130 supports a circular or bull's-eye vial 285. The bull's-eye vial 285 contains a liquid, a gas bubble 290, and at least one marking 295, similar to those already described. The bull's eye vial 285 is used to level a surface or object to be leveled in two directions, where the two directions are perpendicular to each other and the two directions are perpendicular to the planar surface engaging the surface or object to be leveled. As the angle of the level 100 (and therefore the angle of the bull's-eye vial 285) changes, the gas bubble 290 moves within the vial towards or away from the center point of the bull's eye vial 285. The surface or object to be leveled is level with respect to the two directions when the gas bubble 290 is centered within the bull's-eye vial 285. The bull's-eye vial 285 is particularly useful for leveling a drain stack. The bull's-eye vial 285 is secured to the back planar surface 130 using arrangements similar to those already discussed and preferably by threaded set screws.

As shown in FIGS. 1 and 2, the top planar surface 110 includes a channel 300 extending along the length of the top planar surface 110. The channel 300 is curved so the top planar surface 110 can engage a tube, pipe, or other rounded surface for leveling. Alternatively, the channel 300 is notched or V-shaped for engaging a rounded surface for leveling. In other alternatives, the top planar surface 110 is flat. The bottom planar surface 115 includes a notch 305 extending into the web 105. The notch 305 is sized to provide clearance for a seam or other protrusion on the surface or object to be leveled. For example, a vent pipe frequently has a seam that makes it difficult to place the bottom planar surface 115 on the vent pipe. The notch 305 allows the bottom planar surface 115 to be used to level the vent pipe by providing clearance between the bottom planar surface 115 and the seam. Alternatively, the bottom planar surface 115 includes a channel 300 similar to the top planar surface 110. When both the top planar surface 110 and the bottom planar surface 115 include a depression, the two depressions can be sized such that each depression accommodates a rounded surface of a different diameter.

As shown in FIGS. 1 and 2, the top planar surface 110 can include magnets 310 that allow the level to be magnetically attached to a surface or object to be leveled. As shown, the magnets 310 are exposed. Alternatively, the magnets 310 are embedded in the top planar surface 110 (i.e., covered and hidden from view). Preferably, the magnets 310 are neodymium magnets; however, other rare earth or non-rare earth magnets can be also be used. Alternatively, the magnets 310 are supported by the web 105 or other surfaces of the level 100.

As shown in FIG. 1, the top planar surface 110 includes three apertures 315, 320, and 325 extending into the web 105. The apertures 315, 320, and 325 allow the user to view the 0-degree vial 150, the 90-degree vial 155, and the 45-degree vial 160, respectively, through the top planar surface 110. The 30-degree planar surface 125 includes an aperture 330 extending into the web 105 that allows the user to view the 30-degree vial 165 through the 30-degree planar surface.

In the illustrated construction, the level 100 has a length of about 9.50 inches, a thickness of about 0.75 inches, and a height of about 1.375 inches. The features of the illustrated construction may be adapted for use in constructions of the level where the level has a greater or a lesser length, width or height. The level 100 can be constructed from aluminum, steel, plastic, or other suitable material. In addition, other features not discussed could be included on the level 100 or some features discussed could be omitted from the level 100.

FIGS. 9 and 10 illustrate another construction of a level 400. The level 400 includes many of the same features and characteristics of the level 100 shown in FIGS. 1-5. Reference is made to the description of the level 100 for additional characteristics and variations of the level 400. The following description presents additional characteristics and features of the level 400.

As shown in FIGS. 9 and 10, the level 400 includes a web 405 coupled to each of a top planar surface 410, a bottom planar surface 415, a first 45-degree planar surface 420, a second 45-degree planar surface 425, and a back planar surface 430. The top planar surface 410 is spaced apart from and substantially parallel to the bottom planar surface 415. The first 45-degree planar surface 420 is disposed at an included angle of 135 degrees relative to the top planar surface 410 and the second 45-degree planar surface 425 is disposed at an included angle of 135 degrees relative to the bottom planar surface 415. The back planar surface 430 is substantially perpendicular to the top planar surface 410 and the bottom planar surface 415. The back planar surface 430 is connected to the top planar surface 410 by the first 45-degree planar surface 420 and is connected to the bottom planar surface 415 by the second 45-degree planar surface 425.

The web 405 supports a 0-degree vial 435, a 90-degree vial 440, and a 45-degree vial 445, in much the same way as was described with regard to the construction of FIGS. 1-6. The long axis of the 0-degree vial 435 is parallel with the top planar surface 410 and the bottom planar surface 415. The long axis of the 90-degree vial 440 is parallel with the back planar surface 430. The long axis of the 45-degree vial 440 is parallel with the second 45-degree planar surface 425. Each vial contains a liquid, a gas bubble 450, and a series of markings 455.

In some constructions, the 0-degree vial 435, and/or other vials, is a slope gradient vial 435. The slope gradient vial 435 includes a series of slope markings 455 that indicate one-quarter inch, one-eighth inch, and one-sixteenth inch slopes relative to the top planar surface 410 or the bottom planar surface 415. In other alternatives, an integrated shim is included with the slope gradient vial 435 to adjust the longitudinal axis of the vial 435 to the appropriate slope relative to the top planar surface 410 or the bottom planar surface 415.

As shown in FIG. 10, the top planar surface 410 includes an aperture 460 extending into the web 405. As shown in FIG. 9, the bottom planar surface 415 includes an aperture 465 extending into the web 405. The apertures 460 and 465 allow the user to view the vial 435 through the top planar surface 410 and the bottom planar surface 415, respectively. The bottom planar surface 415 includes a channel 470 extending along the length of the bottom planar surface 415. The channel 470 is curved so the bottom planar surface 415 can engage a tube, pipe, or other rounded surface for leveling. Alternatively, the channel 470 is notched or V-shaped for engaging a rounded surface for leveling.

As shown in FIG. 10, the back planar surface 430 supports a circular or bull's-eye vial 475, similar to the one already discussed. The bull's-eye vial 475 contains a liquid, a gas bubble 480, and at least one marking 485.

As shown in FIGS. 9 and 10, a deburring tool 495 is coupled to or formed as part of the web 405. The deburring tool 495 includes a cylindrical aperture with a conical member disposed near one end and extending towards the opposite end of the cylindrical aperture. The deburring tool 495 includes a male side 500 (FIG. 9) and a female side 505 (FIG. 10). An aperture 510 extends into first side of the web 405 and provides access to the male side 500 of the deburring tool 495. The male side 500 includes at least one cutting surface or blade 515 and is arranged to deburr the inside of a tube (e.g., a pipe). To use the male side 500 to deburr the inside of a tube, the tube is inserted into the aperture 510 so that the end of the tube contacts the male side 500. The tube or level 400 is then twisted about the long axis of the tube while in contact with the male side 500 so that the blade 515 cuts away any burrs found on the inside of the tube. An aperture 520 extends into the second side of the web 405 and provides access to the female side 505 of the deburring tool 495. The female side 505 includes at least one cutting surface or blade 525 and is arranged to deburr the outside of a tube. To use the female side 505 to deburr the outside of a tube, the tube is inserted into the aperture 520 so that the end of the tube contacts the female side 505. The tube or level 400 is then twisted about the long axis of the tube while in contact with the female side 505 so that the blade 525 cuts away any burrs found on the outside of the tube. The conical shape of the deburring tool 495 allows both sides 500 and 505 of the deburring tool to be used on tubes of differing diameters. Preferably, the deburring tool 495 is sized to accommodate pipe up to one-inch in diameter, with larger or smaller sizes being possible. The deburring tool 495 is suitable for use with metal pipe or plastic pipe.

As shown in FIG. 9, a chamfering tool 530 is formed by a slot 535 and at least one pair of grooves 540 and 545. The slot 535 extends across the web 405 and through the top planar surface 410 and the bottom planar surface 415. The first pair of grooves includes a first groove 540 through the top planar surface 410 and a second groove 545 through the bottom planar surface 415. The first groove 540 forms a first cutting face 550 and the second groove 545 forms a second cutting face 555. The pair of grooves 540 and 545 is spaced a set distance apart from the slot 535. The set distance corresponds to the diameter of a tube to be chamfered. The slot 535 and the pair of grooves 540 and 545 cooperate to chamfer the end of the tube. The end of the tube is inserted into the slot 535 and the first pair of grooves 540 and 545. The tube or level 400 is then twisted about the long axis of the tube so that the cutting faces 550 and 555 cut a chamfer into the end of the tube. Additional pairs of grooves 560 and 565, 570 and 575, 580 and 585, 590 and 595, 600 and 605, similar to the first pair of grooves 540 and 545, are provided to allow the user to chamfer tubes of different diameters. Preferably, tubes of up to four inches in diameter can be chamfered. A pair of grooves and the corresponding cutting faces can be configured to create an inside chamfer, an outside chamfer, or both on the end of a tube.

A shovel 610 is formed in the web 405 by a depression 615 formed in a first side of the web 405 (FIG. 9) and three slots 620 formed in a second side of the web 405 (FIG. 10). The shovel 610 can be used to dig or clear debris from a work area as required.

FIGS. 11 and 12 further illustrate the level 100. As shown in FIG. 11, the bottom planar surface 115 includes four magnets 700, 705, 710, and 715. The magnet 700 and the magnet 705 are positioned rearward of the notch 305, with the magnet 700 closest to the rear of the level 100 (illustrated as the second connecting surface 145). The magnet 710 and the magnet 715 are positioned forward of the notch 305, with the magnet 715 positioned closest to the front of the level 100 (illustrated as the 30-degree planar surface 125). The magnet 700 is spaced apart from the magnet 705 by a first distance 720, from the magnet 710 by a second distance 725, and from the magnet 715 by a third distance 730. The magnet 705 is spaced apart from the magnet 710 by a fourth distance 735 and from the magnet 715 by a fifth distance 740. The magnet 710 is spaced apart from the magnet 715 by a sixth distance 745. Each of the distances 720, 725, 730, 735, 740, and 745 is measured between the center points of the two associated magnets 700, 705, 710, and 715.

The magnets 700, 705, 710, and 715 are used to releasably magnetically connect the level 100 to an object. In particular, the magnets 700, 705, 710, and 715 are used to magnetically connect the level 100 to an end of a pipe, for example black pipe, galvanized pipe, electrical conduit, and electrical metallic tubing (EMT). The magnets 700, 705, 710, and 715 are spaced apart from one another such that two of the four magnets contact the end of the pipe at opposite sides of the end of the pipe. By using different combinations of the magnets 700, 705, 710, and 715, the magnets may be used to magnetically connect the level 100 to pipes of different diameters. As illustrated, the magnets 700, 705, 710, and 715 are circular. However, the magnets 700, 705, 710, and 715 could be different shapes (for example, ovals or rectangles) to further increase the range of pipes that the magnets 700, 705, 710, and 715 can engage. As shown in FIG. 12, a pipe 717 is magnetically connected to magnets 710 and 715. Typically, the dimensions used to indicate pipe diameters are whole numbers measured in inches. However, an actual outer diameter is larger than the nominal pipe diameter and an inner diameter of the pipe varies based on wall thickness of the pipe. For example, a 6 inch diameter black pipe has an outer diameter of 6.625 inches and has an inner diameter that can vary between 4.897 inches and 6.407 inches depending on wall thickness. In the illustrated embodiment, the level 100 may be magnetically connected to pipes varying in diameter between 1 inch (2.54 centimeters) and 6 inches (15.24 centimeters). In particular, the first distance 720 is 1 inch (2.54 centimeters), the second distance 725 is 4 inches (10.16 centimeters), the third distance 730 is 6 inches (15.24 centimeters), the fourth distance 735 is 3 inches (7.62 centimeters), the fifth distance 740 is 5 inches (12.7 centimeters), and the sixth distance 745 is 2 inches (5.08 centimeters).

In other embodiments, the magnets 700, 705, 710, and 715 are spaced apart at different distances 720, 725, 730, 735, 740, and 745 to accommodate magnetically connecting the level 100 to pipes of different sizes. The bottom planar surface 115 can include additional magnets to increase the number of pipe diameters to which the level 100 can be magnetically connected. As few as three magnets can be used, which results in fewer pipe diameters to which the level 100 can be magnetically connected. Alternately, the top planar surface 110 includes magnets 700, 705, 710, and 715 as described above.

FIG. 13 further illustrates the level 400. The top planar surface 410 includes four magnets 800, 805, 810, and 815. The magnet 800 and the magnet 805 are positioned rearward of the aperture 460, with the magnet 800 closest to the rear of the level 400 (illustrated as the first 45-degree planar surface 420). The magnet 810 and the magnet 815 are positioned forward of the aperture 460, with the magnet 815 positioned closest to the front of the level 400 (illustrated as the shovel 610). The magnet 800 is spaced apart from the magnet 805 by a first distance 820, from the magnet 810 by a second distance 825, and from the magnet 815 by a third distance 830. The magnet 805 is spaced apart from the magnet 810 by a fourth distance 835 and from the magnet 815 by a fifth distance 840. The magnet 810 is spaced apart from the magnet 815 by a sixth distance 845. Each of the distances 820, 825, 830, 835, 840, and 845 is measured between the center points of the two associated magnets 800, 805, 810, and 815.

The magnets 800, 805, 810, and 815 are used to releasably magnetically connect the level 400 to an object. In particular, the magnets 800, 805, 810, and 815 are used to magnetically connect the level 400 to an end of a pipe, for example black pipe, galvanized pipe, electrical conduit, and electrical metallic tubing (EMT). The magnets 800, 805, 810, and 815 are spaced apart from one another such that two of the four magnets contact the end of the pipe at opposite sides of the end of the pipe. As discussed above with respect to FIG. 11, by using different combinations of the magnets 800, 805, 810, and 815, the magnets can be used to magnetically connect the level 400 to pipes of different diameters. As illustrated, the magnets 800, 805, 810, and 815 are circular. However, the magnets 800, 805, 810, and 815 could be different shapes (for example, ovals or rectangles) to further increase the range of pipes that the magnets 800, 805, 810, and 815 can engage. In the illustrated embodiment, the level 400 can be magnetically connected to pipes varying in nominal diameter between 1 inch (2.54 centimeters) and 6 inches (15.24 centimeters). In particular, the first distance 820 is 1 inch (2.54 centimeters), the second distance 825 is 4 inches (10.16 centimeters), the third distance 830 is 6 inches (15.24 centimeters), the fourth distance 835 is 3 inches (7.62 centimeters), the fifth distance 840 is 5 inches (12.7 centimeters), and the sixth distance 845 is 2 inches (5.08 centimeters).

In other embodiments, the magnets 800, 805, 810, and 815 are spaced apart at different distances 820, 825, 830, 835, 840, and 845 to accommodate magnetically connecting the level 400 to pipes of different sizes. The top planar surface 410 can include additional magnets to increase the number of pipe diameters to which the level 400 can be magnetically connected. As few as three magnets can be used, which results in fewer pipe diameters to which the level 400 can be magnetically connected. Alternately, the bottom planar surface 415 includes magnets 800, 805, 810, and 815 as described above.

FIGS. 14 and 15 illustrate another construction that is slightly modified to improve the engagement between the level 900 and the electrical components on which it is placed. FIG. 14 illustrates a side 905 of the level 900 (the switch side) that engages switches. The top and bottom surfaces of the level each include edges that define an outermost plane of the level. Because switches are typically mounted flush with a wall or close to flush with a wall, the rectangular apertures 910 are formed in a surface that is not recessed with respect the remainder of the side 905 of the level 900. In other words, the surface resides on the plane defined by the edges of the top and bottom surfaces. Alternatively, a slight recess may be provided. However, any recess is less than that provided on the opposite side 915 of the level 900. In addition, two symbols 920 are placed on the side 905 shown in FIG. 14. The symbols 920 are indicative of a receptacle and are visible when the opposite side of the level 915 (i.e., the receptacle side) is coupled to one or more receptacles.

FIG. 15 illustrates the receptacle side 915 of the level 900. The arcuate surfaces 910 on the receptacle side 915 are formed in a recess 925 that is sized and shaped to receive a receptacle. Because receptacles typically extend outward beyond a wall a greater distance than do switches, the recess 925 can be employed and are formed on a surface that is disposed between an outermost plane defined by the edges of the top and bottom surface and a central plane of the web. The receptacle side 915 shown in FIG. 15 includes two symbols 930 indicative of switches. The symbols 930 are visible when the switch side 905 is coupled to switches and faces the wall.

In the construction illustrated in FIGS. 14 and 15, the level is arranged to engage one or more light switches such that the level hangs with the long axis being substantially horizontal. When coupled to an outlet, the level is rotated 90 degrees to engage the outlet such that the longitudinal axis of the level is substantially vertical.

Although the invention has been described in detail with reference to certain preferred embodiments, variations and modifications exist within the scope and spirit of one or more independent aspects of the invention as described.
